Now I understand your terminology Peregreno. For a manual "tactical peek" sounds much more official than "porpoise". :D That's loke saying ossifers dine on vagina while NCO's eat pu$$Y. :D

Your assessment of the tactical use of SCUBA is so true. As for the tactical peek, consider where the swimmers came from. Unless it was from an escape trunk of a sub, they were cast from surface craft. Then they had to set their compasses. All of this on the surface. A 5 second peek after 50 meters or so isn't going to be any more compromising.

SF has many other uses for SF swimmers. In Panama we blew channels through the barrier reefs to allow fishermen easier access to the open water. We also blew all of the tree stumps in the Gatun rec areadown to 6 feet under water. In Germany, TURD (Trojan Underwater Recovery Detachment) was used for just that. In Thailand we recovered several submerged T-28s belonging to the RLAF. In Vietnam divers were used to inspect and clear piers and waterways. :lifter

Trip...I agree. I was just answering a question possed by a Civillian Open Water Diver, (who needs to work on his Dive Tables ;) )

I wasn't thinking that R.L. was working up a combat Water OP, unless there's so many Lawyers in L.A. now, that's the only way he can get work. By doing an UW infiltration onto someone's boat and giving them his card. But I doubt that. :D

I just figured he was doing a recreational dive somewhere.

BTW....haven't dove Lake Union. I didn't know there was diving there. What with all the boat and seaplane traffic.

I hope no one is put off by my sharp wit. In reality Sdiver probably gave the best answer to RL's question. I am also a PADI instructor. Constant awareness of one's surroundings is essential.

On the military side many of the exercises we talk of were just that exercises.Several qualified divers who return for requal and/or refressher training could not complete the 2000 M swims.

SF isn't all about kicking doors and launching bullets. There are many uses for SCUBA, especially in the CA?PSYOPS field.

Just kidding Peregrino, although today is the first time I heard the term "tactical peek". I left the army before there was a CDQC.

I'm not sure, I should GOOGLR it, but I think the Q Boat was used to transport, launch and recover the LCSE (Landing Craft Swimmer Reciovery).

Ar one time there were two UW subs in the Pacific. They had a big bulge in the bow and were capable of launching entire team at one yime. Most infilsare by LRB (little rubber boat).

RL check your reading and you will find that most, I think all, UDT operations in WWII wer by surface swimmers. One very tedious operation was the hydrographic survey. Soil samples were collected from the beach and the depth was measured at frequent points using a plumb line. The collect data was charted giving an accurate profile of a beach.

BTW: I just saw a movie titled "Open Water". It is about a couple who was left in the middle of the ocean because the dive master screwed up the head count. I thought it was fairly well done.

Hmmm....dive tables? We don't need no stinking dive tables! We carry two dive computers! :lifter

Just kidding, although I do usually dive with an air intergrated computer as primary and a wrist Suunto Mosquito as a back-up. It is very handy to have these instruments when you are on a liveaboard or a dive vacation where one is diving three dives or more a day. I prefer Nitrox in these circumstances as well. (Old Fart Gas)

I did some commercial Diving in Lake Union in the late 50's and 60's, as well as other places like the Green River/Duwamish Lockheed shipyards, etc. In Lk. Union and some other lakes one could be several feei under the silt visability zero. All was touchy feely. I didn't enjoy my commercial jobs that much. :eek:

Reminds me when we were on Li Ming with the ROC SF. The third day of the exercise all teams got a message had anyone saw the Scuba Team!! :munchin
